FLUSHING- VALVE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed June 1?, 1911. Serial Ho. 883,825.

and State of Illinois, have invented certain new and useful Improvements in Flushing- Vzilves; and I do hereby declare that the following is a full, clear, and exact description of the some, reference being had to the accon'ipunving drawings, and to the numbers of re rence marked thereon, which form a part of this specification.

This invention relates to improvements in flushing valves of that class used in flushing The object of this invention is to afford a flushing valve in which the flushing fluid is chamber 3, and a lower air chamber 4. {Ln inlet ipe 5, connected with the sourc (if water supply, communicates with the water chamber 2, and a discharge pipe '6, reads groin the vent chamber to the fixture it is desired to flush; v Thechumbers2 and 3, are separated by a, pgrtition 7 integral with the casing, and a rclativelylar e operturc therein through which said cgainbers eo muunicateund the upper surface ofsaid partition affords. a valve seat surrounding said aperture. The vent chamber 3, and air chamber g are separated by a partition 8, having a central aperture therein to receive the valve stem 9. therethrough, and, as

; shown, said partition on its under side is at all times separated from the fluid used in g and adapted to receive the packing material retarding the closing of the valve and in which, by no possibility, can either fluid ever enter the chamber appropriated to the other.

It it nlso s n obgoct of the invention to nfi'ord u cllhsing mechanism regulated or controlled by the flow of a fluid other than water and operating in closing partly by gravity.

It is it further objector the invention to all'ord a construction in which the water chamber for the flushing fluid is separated 89 from the chamber for the controlling fluid by an air space or chamber.

It is finally an object of the invention to :itl'hrd an exceedingly cheap, simple and durable device of the class described, in

85 which few parts, and those of very simple construction and operation, are required.

The invention consists in the matters here inufter described and more fully pointed out and defined in the appended. claims.

In the drawings: Figure l is a central vertical section of it device embodying my in vention, showing the some closed. Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a section on line 13- 3 of F ig. 1. Fig. 4 is a.

46 section similar to F ig. l, but showing the valve open or in flushing position. Fig. 5 is an enlarged fragmentary section of the op erating handle. Fig. 6 is a section on line 6(; of Fig. 4:. Fig. 7 is an enlarged frag- 60 mental-y, vertical section til-hen through the regulating chamber, and showing the adjusting valve in elevation.

As shown in the drawings: Said valve comprises a tubule-ceasing l. comprising an upper water chamber 2 an intermediate vent provided with an internally threaded flange 10, concentric with said aperture and stem therein ands. follower 11, affording a gland foxsaid stem. 1

Iivotally supported upon the rear side of the air ehumber l, on a. pintle 1'2, is an operating handle 13, which is yoked to receive the stein 9, therethrough and the arms thereof are longitudinally slotted, as shown in Figs. 1. 3 and 4, to receive-n pin 14, enga ed in said stem, this arrangement permitting suitl stem to be raised by means of said lover. The outer end of said handle or lever is externally threaded and an ornamental or (hinges 17, of which is threaded the-uppereiul of u cup 18, for oil or other suitable regulating fluid. Said cup is cylindrically bored and provided with a lower closed head 1) (preferably integral therewith) and on the lower ,cnd of said stem 9, which projects into the chamber 20. thus formed, is secured a piston "embracing upper and lower plates 31 and 22. threaded on the end of said stem and between which is engaged a hydraulic'pncking washer-23, which is flanged at its edges downwardly to permit the same to yield readily when the stem is adjusted upwardly but to permit the some to resist downward movement of the stein;-

, connect d a gland 24, is provided on the c2. side oi and the head 16,- surrounding said st in. A. bypass passage is cored at one 'rela U communicating with the regulating chamber near the upper end thereo and, as shown, a needle valve closure 28, is threaded through the wall of said by-pass passage in position to be adjusted inwardly or outwardly to vary or regulate the flow through said ventfrom the by-pass to the regulating chamber. As shown, said necdle valve closure is provided with a gland 29, surrounding the same to prevent the leakage of the oil or other regulating fluid, therepast. A head or cover 30,

is threaded on the upper end of said casing to all'ord the top wall of the water chamber and a downwardly projecting stud or guide pin is secured at the center thereof at the axis of said chamber and stem. The

upper end of said stem extends ipto the vent cluin'ibcr and to near the partition 7, and there is reduced in diameter or otherwise provided with an upwardly directedshoul-v 39 der 32, and seated on the upper end and hearing on said slimilder, is astenl section 33. provided with an axial aperture in its upper end to receive the pin 31, therein, as shown in Fig. I. Said stem section is provided at its lower end with a peripheral i a i flange 3d, and is or relatively large d1amcter and at its sides is fluted or out way rendering the same non-cyl1ndr1c. Shdably seated upon said stem section 153 ashort exso tcrnallv threaded sleeve 34;, provided at its lower end with an outwardly extending flange 3 3,'and having secured thereon a packing washer 36, and a nut 37. Said packing washer and a nut are of a diameter greater than the aperture through the partition 7,

and seat to close said aperture except for the water passages at each side of the stem sections, as shown in Fig. 2. Said stem S807 tion, approximately at the topof the valve o closure thus formed, 18 reduced in diameter to afford an upwardly directed shoulder 38, and slidablv secured on said stem section above theshouldcr, is sleeve 39, provided its bottom with an integral flange 40,

in which is seated a packing Washer 41,

which seats u por the upper end of the sleeve 34, to entirely close the passages on each side of said stem section and through the sleeve 34, said construction affording a relatively so large main closing valve 'and an auxiliary or vent valve operating therewith to complete the closure.

- The operation is as follows: The weight of the handle and stem,-as well as the pressure 55 of water upon the valves in the water chamher, acts to hold the valves at all times closed normally. lVhen it isAl esired to use the valve in flushing, the stem is raised against gravityby means of the handle 15. This simultaneously raises the ventvalve clo sure. opening the ports or passages on each side the vaLve stem section through the main valve closure, reducing the pressure thereby, and also raises the piston in the bottom of the regulating chamber or compartment, the oil ul' other liquid flowing freely past the hydraulic washer or packing therefor. As the stem rises,the flange 34, at the lower end of the stem section, engages beneath the main valve closure, as shown in Fig. 4, and lifts the same from its seat wholly opening the valve, and permitting free flow of the flushing fluid to the fixture. The valve, of course, may be held open as long as desired by simply holding the stem in elevated position. as shown in Fig. 4. \Vhen the handle is released. the closing movement begins. This is caused by gravity, the handle now acting by gravity to force t-hestern downwardly. the force exerted, of course, being dependent upon the weight of the parts. Of course, the handle may be made of any desired weightby supplying a heavy material such as lead or the like in the handle 15, if desired.

The rate of downward movement is regulated by the tlow of the regulating fluid through the by-pass passage as controlled by the needle valve 28. If quick closure is desired, of course, a larger opening-of the port lor vent between the bypass passage and the regulating chamber is permitted. As the stem descends, the main valve closure first seats. This occurs noiselessly and without hammer, owing to the construction described, and the main flow of the fluid is thus'dis continued. The water continues to flow through the ports or passages at each side of the stem section, however, until the stem hasdescendcd sutiiciently to permit thaux;

iliary or vent valve closure seating. Thisq atlords the after fill for the fixture, and, of course, ceases when the vent or auxiliary valve closure se'a'ts upon the main valve closure, as shown in Fig. 1.

From the construction described, it is obvious that oil or the regulating fllil can never esca e from its containing chamber, as only a su cient quantity is contained therein to suliioe forthe comparatively limited movement of the stem. Watercan never find ingress to said re" lating chamber, owing to the glands be iie described between the vent chamber and the regulating chamber, and because of the air chamber or compartment arranged between said two ,chambers. Of course, inasmuch as the air ch amber opens outwardly t the atmosphere, any moisture finding its way thereinto evaporates and escapes therefrom. No

springs whatever are used in the construction. The valve is positive and quick in operation, and the rate of closure of the valves may be adjusted at will by means of the valve in communication between the regulating chamber and by the by-pass passage. Said valve, of course, may be placed either at the top of said passage, as shown in Figs. 1 and 2, or at the bottom thereof, as desired. In either position a screen 41, just above the lower port 26, strains the oil, thereby preventing clogging of the regulating valve 28.

Any part of the flushing valve is accessible for inspection and repair without disconnecting from the water system or from the toilet' This is accomplished by removing the cap 30, or the cup 18, containing the regulating fluid. Of course, the water should first 'be shut off by the usual valve controlling the How to the flushing device.

I do not purpose limiting the patent granted on this application otherwise than necessitated by the prior art, for very numerous details of construction and operation may be varied without departing from the principles of this invention.
